What an alarm looks like

Not a quiet ping. Every phone on your team rings.

Call, text, email and push to everyone on your list, plus a loud buzzer on site. It repeats until the walk-in is back in range.

Example alert. You name your devices and set your own limits.
Health inspection ready

The inspector walks in. Your logs are already done.

No clipboards and no missed checks. EDGE logs every cooler and freezer on its own, time-stamped, day and night.

  • Records that write themselves

    Every reading is saved and time-stamped automatically. WiFi or power drops? EDGE keeps recording and uploads every missed reading when it reconnects. No gaps.

  • Every alarm signed off

    Staff acknowledge with a note. The log keeps who handled it, when, and what they did.

  • Show the inspector in seconds

    Pull up any day on a phone or laptop. Free forever: 45 days online plus Excel export anytime, and the files are yours to keep. Want one-click PDF reports and full history? Premium: first year included, then about $17.78/yr (about $1.48/mo), billed annually.

Questions owners ask before they buy

What happens when the power goes out?+

Keep EDGE Thermo Cellular plugged into USB-C power, with its 4 AA batteries standing by. When the power drops, it sends a power-outage alert to your whole team by push, email and text (each person on the channels turned on in their own profile) at its next recording (within 10 minutes at the default 10-minute recording interval, about a minute if it records every minute), and the batteries take over (up to 2 years on AA batteries alone), so it keeps logging and alarming through the outage. It doesn't need your WiFi router, which goes down with the power: it has its own cellular link. The WiFi model also keeps logging on its batteries, but it can only send alerts while your router and internet are up.

What if the batteries die or a sensor stops working?+

You'll hear about it. AA batteries last up to 3 years in the WiFi model and up to 2 years in the Cellular model, depending on settings, and EDGE shows a low-battery indicator and emails you a low-battery alert, so a battery swap is planned, not a surprise. If a device stops reporting for any reason (flat batteries, unplugged, out of range), a no-connection alarm tells you. And if the network drops, EDGE keeps recording and uploads every missed reading when it's back, so your log has no gaps.

Who gets the alarm, and what do alerts cost?+

As many people as you want: owner, chef, night manager, maintenance, the morning crew. On WiFi, adding new people after the first year needs Premium; everyone already on the list keeps their alarms. Every alarm goes out by automated phone call, text, email and push, and repeats until the reading is back in range. Email and push alerts are free and unlimited forever. Texts and calls run on prepaid alert credit: every device ships with about $3.70 of credit (enough for 250 texts or 100 calls), then it's about 1.5¢ per text and about 3.7¢ per call, so a 3 a.m. call to 5 people costs about 19¢. Top up online anytime, and if the credit ever runs out, email and push alerts keep going.

Is there a monthly fee?+

Not on WiFi models: the first year of Premium is included, then the free Standard plan keeps live data, every alarm and 45 days of history at $0 a month (Premium, with advanced reports, full history and sharing with new people, is optional at about $17.78/year, about $1.48/month, billed annually). EDGE Thermo Cellular includes its first year of cellular data; after that it's about $26.67/year (about $2.22/month, about 7.4¢ a day), billed annually, with unlimited data and no carrier contract. Nothing is charged before year two.

Does MaxLinc help with HACCP records and health inspections?+

Yes. Every reading is logged automatically and time-stamped, so your HACCP temperature records build themselves. When an inspector or food-safety auditor walks in (in Canada, CFIA or provincial; in the US, state or local), pull up any day on your phone or laptop in seconds. The free WiFi plan keeps your last 45 days online, and you can export to Excel anytime and keep the files as long as you need; Premium (about $17.78/year, billed annually, first year included) keeps your full history online and adds PDF and advanced reports.

What if my kitchen doesn't have reliable WiFi?+

Choose EDGE Thermo Cellular. Its built-in cellular link (global eSIM) sends your alerts and readings without WiFi, a router or any IT setup, which makes it ideal for walk-ins out of WiFi range, food trucks and catering vans.

How many devices do I need?+

One EDGE Thermo has two external probes, each with its own limits and alarms, so one device watches a cooler and a freezer side by side. Each probe comes on a 1.5 m (4.9 ft) cable and extends to 16.5 m (54 ft) in total with 3 m (10 ft) extension cables; extend both probes by about the same length (within 3 m (10 ft) of each other). For walk-ins farther apart, plan one device per walk-in, or send us your layout and we'll map it for free.

Will I get an alert if a walk-in door is left open?+

Yes. A door left open shows up as a temperature rise within minutes, and the alarm fires the moment a reading crosses your limit, by phone call, text, email and push to everyone on your alert list, repeating until the reading is back within your limit. Staff can acknowledge the alarm with a note on what they did, and the log keeps their name, the time and the comment. The EDGE Thermo also has a digital input for an optional door contact if you want a dedicated door-open alarm; ask us when you request your plan.

How hard is it to set up?+

Setup takes under 5 minutes: register the device in the web app, connect it to your WiFi (the Cellular model needs no WiFi setup at all), put the probes in your cooler and freezer, set your limits and add your team. No wiring and no app-store download: it works in the browser on any phone or computer.

What if it's not right for my kitchen?+

You're covered by our 30-Day Money-Back Guarantee: send back any unused item in its original packaging within 30 days and we pay the return shipping. Plus a 2-year limited warranty from the date of purchase (your invoice date). Questions before you buy? Call a real person at 1-888-365-8880.
